JOURNAL-BOX.

Specification of Letters Patent. Patented 17, 1918.

Original application filed November 8, 1913, Serial No. 779,941. Dividedand this application filed March 16,

To all whom it may concern Be it known that I, CLAYTON MARK, a citizenof the United States, residing atLake Forest, Lake county, Illinois,have invented new and useful Improvements in Journal- Boxes, of whichthe following is a specification, reference being had to theaccompanying drawings, in which Figure l is an elevation of a journalbox embodying my invention; Fig. 2 is a plan thereof partly broken awayon lines IIII of Fig. 5; Fig. 3 is a section on lines III-III of Fig. 2;Fig. 4. is a partial rear elevation; Fig. 5 is a section on lines V-V ofFig. 2, and Fig. 6 is a section on lines VIVI of Fig. 2.

My invention relates to journal boxes, and consists in a journal boxcomprised of two or more parts, in which the top is preferably made ofcast metal and the bottom, or oil cellar, is preferably made of ressedor stamped metal, and in uniting tiese parts together by welding.

Various other features comprising my invention are hereinafter describedand claimed, the method, however, being claimed in my pendingapplication, Serial Number 7 7 9,941, filed November 8, 1913, of whichthe present application is a division.

Referring to the drawings, A indicates the top of the journal box,preferably comprised of cast metal, such as malleable iron or steel,because of its somewhat intricate shape, and having the usual hinge lug2, and the. journal bearing side stops 3. B indicates the bottom part oroil cellar, and C the dust guard wall, both of which are preferably madeof pressed steel. The oil cellar B is preferably made without the usualstrengthened ribs, and with its top edges 4; unbroken, so that they beardirectly against the underface of the top A.

Extending downwardly from the top A are flanges 5, which are adapted toenter inside of the top edges 4L of the oil cellar B and to fit closelythereagainst. When these parts 4 and 5 are thus interengaged they aresecured or bonded together by welding. The uniting of the parts may beeffected by continuously welding together the contacting faces of theflanges 5 and the top edges l into an integral structure.

faces. In either event the result is that the top A and oil cellar B aremade, in effect, If desired, the parts may also be welded along thelinesc and (Z.

The dustguard wall C fits closely in the rear end of the oil cellar Band forms the inner wall of the dustguard chamber 9. The member C hasinwardly-turned flanges 7 and 8 in its lower ortion, which bear againstthe bottom and sides respectively, and in its upper portion it has alsooutwardly-turned flanges 10, which bear against the sides of the oilcellar B. The member 0 may be welded to the top A and bottom B along theflanges 7, 8 and 10 where these flanges bear against the inner surfacesof the bottom I made much lighter without necessitating any sacrifice instrength, and with a slight increase in the thickness of the metal theboxes may be made without the usual strengthening ribs. It is, however,not necessary that the bottom of the box be made to withstand thestrains to which the top is subjected, since normally the bottom actsmerely as an oil cellar, practically all of the strains beingtransmitted through the top to the side frame, so that fromconsiderations of lightness and cheapness the bottom may be made of muchlighter metal than the top.

If desired, the connection between the top and the oil cellar may bemade by butt welding the upper edges of the oil cellar against the undersurface of the top, as is shown at c in Fig. 6, in which case thedownwardly extending flanges will act as reinforcements for the parts.

The terms and expressions herein used are used as terms ofdescriptionand not of limitation, and I have no intention in the use of such termsand expressions to exclude any mechanical equivalent for the featuresshown and described, but recognize that various structural modificationsare possible within the scope of the invention claimed.

What I claim is:

1. A journal box comprised of a cast metal top, a pressed metal oilcellar, the rear wall thereof forming the outer wall for a dustguardslot, and an inner dust-guard Wall, said Wall being contained in thepressed metal oil cellar and having flanges adapted to be secured to theoil cellar by Welding, said flanges having a bearing on the rear Wall ofthe oil cellar, and determining the position of the inner dust-guardwall with relation to the rear Wall of the oil cellar.

2. A journal box having its rear Wall forming the outer Wall of adust-guardslot, and an inner dust-guard wall, said wall be- Gopies ofthis patent may be obtained for ing wholly contained in said box andhaving oppositely-directed flanges, one of the flanges determining theposition of the inner wall with relation to the rear Wall of the box andanother of the flanges serving as means for attaching the inner Wall tothe box.
